Broadcast signal transmission/reception device and method

A device for processing broadcast signals, the device comprising:

• a tuner configured to receive the broadcast signals including components for a service and signaling information for the service, wherein the portion of the components for the service or the duplicate of the components for the service is delivered via multiple RF channels,
• wherein the signaling information includes a first BSID representing a first broadcast stream in which a first set of components of the service is delivered, a service ID representing the service, a major channel number of the service, a minor channel number of the service and other BSID information,
• the other BSID information includes a second BSID representing a second broadcast stream for the service and type information representing a type of a second set of components delivered in the second broadcast stream,
• the type of the second set of components is either a portion of the service components for the service or a duplicate of the service components for the service;
• and
• a demodulator configured to demodulate the broadcast signals.

A broadcast signal transmission apparatus, comprising:

• A processor configured to processing components for a service, signaling information for the service,
• wherein the signaling information includes a first BSID representing a first broadcast stream in which a first set of components of the service is delivered, a service ID representing the service, a major channel number of the service, a minor channel number of the service and other BSID information,
• the other BSID information includes a second BSID representing a second broadcast stream for the service and type information representing a type of a second set of components delivered in the second broadcast stream,
• the type of the second set of components is either a portion of the components for the service or a duplicate of the components for the service;
• and
• a transmitter configured to transmitting the broadcast signals including the components for the service and the signaling information for the service, wherein the portion of the components for the service or the duplicate of the components for the service is transmitted via RF channels.
